Aromas of rosemary and lavender essential oils differentially affect cognition and mood in healthy adults.

Abstract: This study was designed to assess the olfactory impact of the essential oils of lavender (Lavandula angustifolia) and rosemary (Rosmarlnus officinalis) on cognitive performance and mood in healthy volunteers One hundred and forty-four participants were randomly assigned to one of three independent groups, and subsequently performed the Cognitive Drug Research (CDR) computerized cognitive assessment battery in a cubicle containing either one of the two odors or no odor (control) Visual analogue mood questionnaires were completed prior to exposure to the odor, and subsequently after completion of the test battery The participants were deceived as to the genuine aim of the study until the completion of testing to prevent expectancy effects from possibly influencing the data The outcome variables from the nine tasks that constitute the CDR core battery feed into six factors that represent different aspects of cognitive functioning Analysis of performance revealed that lavender produced a significant decrement in performance of working memory, and impaired reaction times for both memory and attention based tasks compared to controls In contrast, rosemary produced a significant enhancement of performance for overall quality of memory and secondary memory factors, but also produced an impairment of speed of memory compared to controls With regard to mood, comparisons of the change in ratings from baseline to post-test revealed that following the completion of the cognitive assessment battery, both the control and lavender groups were significantly less alert than the rosemary condition; however, the control group was significantly less content than both rosemary and lavender conditions These findings indicate that the olfactory properties of these essential oils can produce objective effects on cognitive performance, as well as subjective effects on mood

Critical Community Psychology

Abstract: Critical Community Psychology is written by a group of academic community psychologists with many years of experience working, teaching and thinking together. They have developed a clear and effective method for bringing together the theory and practice of community psychology, which has become firmly grounded in time and place. This book aims to provide students of different community-based professions, working in a range of applied settings, with not only the theories, values and principles of community psychology, but also with the practical guidance that will underpin their community psychological work.

The researched opinions on research: visually impaired people and visual impairment research

Abstract: In this paper, we describe our research review, commissioned by 'the Gift of Thomas Pocklington', into the opinions of visually impaired people on visual impairment research. We interviewed 37 visually impaired people across Central Region, Scotland. Our findings suggest areas of need for visual impairment research, both concerning what is researched and how it is researched. We make recommendations for future research addressing both resource and methodological issues. We suggest increasing resources for recruiting participants and multimedia dissemination (e.g. audio tape, Braille, Moon). Methods may need to be refined to address difficulties in recruiting participants, and to capture the diversity of strengths and needs of visually impaired people. We make three core recommendations that identify the need for research to: respect people's individuality; be practical and action orientated, and contribute to an empowering and emancipatory research agenda. We conclude by reflecting on our role as communit...

Disability and participation: It's about us but still without us!

Abstract: Participation is often espoused as a strategy to promote inclusion, social justice and equality. Exactly how to facilitate participation in practice is often not explicated, nor are the challenges or issues highlighted. By drawing on interview data, the first aim of this paper is to identify the key barriers to participation in an organizational planning activity as experienced by 12 disabled and non-disabled staff and board members in a small community-based disability advocacy organization. The second aim is to draw upon Jim Ife's principles of participation to further analyse the factors that hinder and enable participation in organizations. Reported barriers to participation were categorized at individual, interpersonal and organizational levels of analysis, and included a lack of skills and competence, interpersonal conflicts, poor resourcing and ad hoc processes. The importance of understanding the dynamic interplay of individual and structural factors, valuing different forms of participation and having participatory structures and processes embedded in organizational settings are all highlighted. This study illustrates that, even in an organization that is specifically attuned to meeting the needs of disabled people, there is still considerable exclusion and institutional discrimination. Strategies to promote participation within an organizational context may include providing sufficient time for reflection and support, and opportunities for board members to learn how to take part in constructive planning activities and to develop their strengths.

The Schools We Deserve@@@A Place Called School: Prospects for the Future

Abstract: This is an account of the largest on-the-scene study of U.S. schools ever undertaken. Called A Study of Schooling' and carried on over 4 years, trained investigators went into more than 1,000 classrooms in 38 elementary and secondary schools in seven different sections of the United States. These schools were located in urban, rural, and suburban areas. The investigators talked to teachers, students, administrators, school board officials, parents, and other members of the community. The result is this landmark report, written by one of the country's most astute and experienced educators. His message is one of cautious optimism, despite the extensive problems uncovered, and he provides a realistic agenda for improvement. This report will be a rich and stimulating resource for all those concerned with the education of our youth.

Microencapsulation of Oils: A Comprehensive Review of Benefits, Techniques, and Applications

Abstract: Microencapsulation is a process of building a functional barrier between the core and wall material to avoid chemical and physical reactions and to maintain the biological, functional, and physicochemical properties of core materials. Microencapsulation of marine, vegetable, and essential oils has been conducted and commercialized by employing different methods including emulsification, spray-drying, coaxial electrospray system, freeze-drying, coacervation, in situ polymerization, melt-extrusion, supercritical fluid technology, and fluidized-bed-coating. Spray-drying and coacervation are the most commonly used techniques for the microencapsulation of oils. The choice of an appropriate microencapsulation technique and wall material depends upon the end use of the product and the processing conditions involved. Microencapsulation has the ability to enhance the oxidative stability, thermostability, shelf-life, and biological activity of oils. In addition, it can also be helpful in controlling the volatility and release properties of essential oils. Microencapsulated marine, vegetable, and essential oils have found broad applications in various fields. This review describes the recognized benefits and functional properties of various oils, microencapsulation techniques, and application of encapsulated oils in various food, pharmaceutical, and even textile products. Moreover, this review may provide information to researchers working in the field of food, pharmacy, agronomy, engineering, and nutrition who are interested in microencapsulation of oils.

Essential Oils Loaded in Nanosystems: A Developing Strategy for a Successful Therapeutic Approach

Abstract: Essential oils are complex blends of a variety of volatile molecules such as terpenoids, phenol-derived aromatic components, and aliphatic components having a strong interest in pharmaceutical, sanitary, cosmetic, agricultural, and food industries. Since the middle ages, essential oils have been widely used for bactericidal, virucidal, fungicidal, antiparasitical, insecticidal, and other medicinal properties such as analgesic, sedative, anti-inflammatory, spasmolytic, and locally anaesthetic remedies. In this review their nanoencapsulation in drug delivery systems has been proposed for their capability of decreasing volatility, improving the stability, water solubility, and efficacy of essential oil-based formulations, by maintenance of therapeutic efficacy. Two categories of nanocarriers can be proposed: polymeric nanoparticulate formulations, extensively studied with significant improvement of the essential oil antimicrobial activity, and lipid carriers, including liposomes, solid lipid nanoparticles, nanostructured lipid particles, and nano- and microemulsions. Furthermore, molecular complexes such as cyclodextrin inclusion complexes also represent a valid strategy to increase water solubility and stability and bioavailability and decrease volatility of essential oils.
